CALGARY — Penn West Petroleum Ltd. stock fell to a new 52-week low Tuesday after the company announced four vice-presidents stepped down.Penn West shares dropped 3.5 per cent or 41 cents to $11.19 on the Toronto Stock Exchange after earlier falling as low as $11.05.The Calgary-based oil and gas producer said the senior executives whose departure was effective immediately are: Hilary Foulkes, executive vice-president and chief operating officer; Thane Jensen, senior vice-president and operations engineering; James Burns, vice-president of corporate planning; and Wendy Henkelman, vice-president, treasury.The company did not offer an explanation beyond that “improved execution is the key to realizing the value inherent in the company’s asset base.”“We will continuously make the necessary changes to deliver on our business plan,” it said.The company has been restructuring, partially to pay down debt.Penn West agreed in principle last month to sell $1.3-billion worth of its non-core properties, representing the equivalent of 12,000 barrels per day of production.The Calgary-based company said it would use funds from the sale to repay a portion of the money drawn on its credit facilities.“Recently announced agreements to sell assets have provided Penn West with operational and financial flexibility, allowing the company to maintain its dividend while applying capital to high rate of return projects in its portfolio,” it said in a release Tuesday.The company has been positioning itself to concentrate on light-oil plays, particularly along the Cardium formation in southern Alberta.During the most recent third-quarter, risk management activities helped pushed the oil and gas producer into the red. Last week, it reported a net loss of $67-million or 14 cents per share in the quarter.That compared with year-earlier net income of $138-million or 29 cents per share.The big swing was mainly due to unrealized losses or gains on the company’s risk-management contracts, partially offset by unrealized foreign exchange gains and losses.By other measures, Penn West had a more stable quarter.Revenue was $840-million, down from $861-million a year earlier. Funds flow was $344-million or 72 cents per share, down from $348-million or 74 cents per share. Production fell to the equivalent of 160,339 barrels of oil per day from 161,323 barrels per day.
Public Health Minister Seema Kennedy said: “Over 30 years ago we introduced the MMR vaccine and since then our world-leading vaccination programme is estimated to have prevented 1.8 million painful and potentially fatal cases of measles.”No child or young person should have to suffer from mumps, measles or rubella, and we must curb this recent increase in cases so we don’t see a return of horrible diseases of the past.”By taking up the MMR vaccine parents and young people can prevent more cases and I would urge everybody to do so.”The MMR vaccine is given on the NHS as a single injection to babies as part of their routine vaccination schedule, usually within a month of their first birthday. A second injection of the vaccine is given before starting school, usually at three years and four months.The vaccine is also available to all adults and children who are not up to date with their two doses.PHE said that anyone who is not sure if they are fully vaccinated should check with their GP.

PHE warned that because measles is highly infectious, anyone who has not received two doses of MMR vaccine is at risk.Unvaccinated people travelling to countries where there have been large outbreaks of measles are particularly at risk, it added.The public health agency said that 94.9% of eligible children aged five received their first dose of MMR in the final quarter of 2018, with coverage of the second doses at 87.4% for children aged five.One dose of the MMR vaccine is about 90-95% effective at preventing measles, rising to around 99% after the second.To achieve herd immunity for measles at least 90-95% of the population needs to be fully protected. Head of immunisation Dr Mary Ramsay warned that with measles outbreaks across parts of Europe families should make sure they are vaccinated before they travel.She added: “Measles can kill and it is incredibly easy to catch, especially if you are not vaccinated.”Even one child missing their vaccine is one too many – if you are in any doubt about your child’s vaccination status, ask your GP as it’s never too late to get protected.”There are measles outbreaks happening across Europe so if you are planning to travel, make sure you check with your GP and catch-up if needed.”There have been 3,789 cases of measles across the continent during the first three months of this year according to the European Centre for Disease Prevention and Control. The highest numbers have been in Romania, France, Poland and Lithuania, its latest data from May 10 revealed. Parents are being urged to get their children vaccinated for measles, mumps and rubella following outbreaks of measles across Europe.The appeal comes on the same day new figures revealed there had been 231 confirmed cases of measles and 795 mumps cases in the first three months of 2019.The Public Health England (PHE) data showed that while measles cases were lower than the 265 during the same period last year, they had more than doubled compared to the 97 reported between October and December.Mumps cases nearly tripled to 795 compared to the 275 during the same period last year, with no new cases of rubella reported.PHE has urged parents to make sure their children receive the MMR vaccine when offered it or to take it up now if they missed it.
